12 Days of Trekking to Annapurna Base Camp Maximum Elevation 3900 metres (12,800 feet) The route to Annapurna Sanctuary (Annapurna Deuthali in Nepali), the site of the Annapurna south face base camp, is a spectacular short trek. Though it has some steep climbs, the trek is not difficult. The major problem with this trek is that it can become impassable because of snow and avalanches in winter and early spring. It is the only major trekking route in Nepal that has significant avalanche danger, so you must inquire locally whether the trail is safe. Some trekkers have died because of avalanches, and others have been stranded in the sanctuary for days. The sanctuary trek traverses a variety of terrain, from lowland villages and rice terraces to glaciers, and offers outstanding high mountain views. This trek is a fine opportunity to surround yourself with Himalayan peaks in a short time, without having to contend with the altitude and flight problems of the Everest region.
